Merge branch 'sja1105-stats'

Vladimir Oltean says:

====================
Ethtool statistics counters cleanup for SJA1105 DSA driver

This series removes some reported data from ethtool -S which were not
counters at all, and reorganizes the code such that counters can be read
individually and not just all at once.
